Disclosed is an automatic transfer switch. According to the exemplary embodiment of the present invention, the automatic transfer switch alternatively supplying power from a commercial power terminal and an emergency power terminal to load terminals by moving a pair of movable contactors, wherein at least one of the pair of movable contactors are integrally formed with the commercial power terminal or the emergency power terminal through a wire made of a flexible material.

Automatic transfer switch

Provided is a one body-type power transfer switch, in which a disconnecting portion is integrally formed to reduce errors arisen due to accumulated assembly tolerance and simplify manufacturing processes, thereby improving operators' convenience. The one body-type power transfer switch includes a normal power terminal or an emergency power terminal, a module including a load terminal formed at a lower portion of a side of the module so as to be spaced apart from the normal power terminal or the emergency power terminal, wherein the module is formed using an injection molding method, and side walls are integrally formed to have insulating power.

One body-type power transfer switch

Provided is a cover for protecting an upper end of a normal power terminal and an upper end of an emergency power terminal of an auto transfer switch. In this case, terminal covers are formed on the upper ends of the terminals to protect the terminals, thereby preventing operators from being hurt by electric shock.

Auto transfer switch including terminal cover

A cover of an electrically-connected portion of an auto transfer switch, which is detachable and includes an arc guide portion.
